I am amazed how sturdy and well made this island is!  When I opened (very well and carefully packaged, by the way) the box I expected flimsy material etc., but found it well exceeded my expectations.  I also love the good casters.  (they are usually of poor quality and won't roll well, but these do!)  It moves about with ease, so much so, that I might just leave it up all the time rather than folding down and storing.  Even with weight on the shelves it moves easily.  Can't say enough good about it!
